UNITED STATES PATENT TORGER 'IVEDLER, OF CAMBRIDGE, IOIVA.

AGRICULTURAL BOILER OR BARREL-HEATER.

SPECIFICATION forming part of Letters Patent N0. 395,762, dated. January 8, 1889.

Application filed March 3, 1888. Serial No. 266,0 18. (N0 model.)

T0 to whom, it may concern.-

Be it known that I, TORGER TVEDLER, a citizen of the United States, residing at Cambridge, inthe county of Story and State of Iowa, have invented certain new and useful Improvements in Agricultural Boilers or Barrel-Heaters; and I do declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom-. panying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The special object of the invention is to improve such barrel-heaters or agricultural boilers as are described in Patents Nos. 135,005, 206,319, and 209,13-l. The boilers or barrel-heaters described in these patents have the fire-place at the base, while I make mine about the middle of the height of the barrels and between them. By this construction the fire-heat is applied more uniformly and with less heat-waste either to one or both of the barrels, while it also enables me to have a hot-water tank directly over the lire-place, where steam may be also generated and supplied through a hose for thawing the ice in troughs or vessels of any kind.

Another object which I have in view is to utilize the escaping products of combustion for smoking meat, fish, and other things, as hereinafter described.

Figure I of the drawings is an elevation in perspective of my barrel-heater; Fig. 2, a horizontal section thereof, and Fig. 3 is a vertical cross-section on dotted line we: of Fig. 2.

In the drawings, A represents the ground floor; I the brick-work shell; 0, the iron fire-place; D, the fuel-door; E, the aslrdoor, and F the Smokestack.

G is a hot-water tank located directly over the tire-place G, and provided with an eduction-tube, g, for .receiving a hose-pipe, through which steam may pass out and be used for melting ice in troughs or other vessels. H II are the feed barrels, vats, or receptacles for the food which is to be cooked. Each barrel. II is made in three sections, h 72. 71 the middle one of metal and the end ones of wood. Around the middle metallic section, 71., is the brick-work or wall 13, between which and the metallic section is the fire or smoke due I), through which the products of combustion pass to the smoke-stack F. In the latter I make a damper, f, and just below it connect the smoke-stack with a chamber, K, which has an i11let-pipe,7u,at the bottom and an outlet-pipe, 7e, at the top, the latter connecting with a smoke-stack, L, or above the damper with the smoke-stack F.

Having thus described all that is necessary to a full understanding of my inventiomwhat I claim as new, and desire to protect by Letters Patent, is-

The combination, with a brick-shell median tire-place and smoke-stack, of two feedbar rels, one on each side of fireplace and extendingboth above and below it, a space be tween shell and barrels forming a flue, f, leading to the smoke-stack, as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses. TORGER TVEDLER.
